FEEDER FOR BAGASSE=F URNACES.

SPECIFICATION forming part of Letters Patent No. 364,871, dated June 14, 887. 1

Application filed March 28, 1887. Serial No. 232,709. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM WATsoN TAY- LOR, a subject of the Queen of Great Britain, I

residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Feeder for Bagasse-Furnaces,

' of which the following is a specification.

My invention relates to improvements in roller-feeders for feeding the bagasse from a sugarunill into a bagassefurnace.

The object of my improvement is to provide self adjusting rollers that will admit more or less bagasse through them, according to the supply from the bagasse-carrier. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a plan of the feeder complete. Fig. 2 is a front view. Fig. 3 is an end view. Fig. 4 is an end view, to an enlarged scale, of part of one of the rollersandth'e arrangement of spiral springs, sliding-boxes, &c., which allow the roller to be self-adjusting. Fig. 5 is alongitudinal section of roller. Fig. 6 is an end View of roller.

Similar letters refer to like parts in all the figures.

Feeding-rollers that revolved in stationary boxes were first used to feed bagasse-furnaces. It was found that these would choke frequently, on account of the unequal feed of ha ga'sse. making one of the rollers to work in sliding boxes, so that the rollers would open to admit uneven quantities of bagasse, and would close up again by means of levers and weights; but it was found that, although much better than the non-adjustable rollers, the lever-audweight system did not work satisfactorily on account of friction of the fulcrum of the lever and consequent slowness of action of the roll- BPS.

gether, and the roller F is adjusted to the An improvement was then made by ers. N is an adjustable screw to prevent the roller F coming out too far, in which case the wheels H H might come out of gear. The action of the spiral springs on the sliding roller is quick and effective, and answers every desired purpose.

G is the hopper into which the bagasse falls from a bagasse-carrier. H are a pair of longtoothed spur-wheels that gear the two rollers together. I is the pitch-wheel, that is driven by a pitchchain from a bagasse-carrier. Under the hopper G is the casting J, that fits into a hole in brick-work at top of furnace.

The roller K, Figs. 5 and 6, shows the con struction of one of the rollers. I make the roller of a piece of wrought-iron pipe, riveted onto cast heads L, which heads are keyed fast on shaft M. This construction makes a light and strong roller, and one that does not require turning on the outside, as must be done when cast-iron is used, which is necessarily heavier and irregular, and more expensive.

\Vhat I claim, and desire to secure by Let ters Patent, is

1. The combination, with the hopper for feeding bagasse to a furnace, of a roller journaled in stationary bearings on one side of said hopper, a roller arranged in sliding boxes on the opposite side of said hopper, springs acting on the sliding boxes, and wheels gearing the two rollers together at one end, so that they rotate in unison, substantially as described.

2. The combination, with the hopper G, for feeding bagasse to a furnace, of a roller, D, j ournaled in stationary bearings E 011 one side of said hopper, a roller, F, journaled in sliding boxes B on the opposite side of said hopper, springs A,acting on the sliding boxes, gear-wheels II, directly gearing the rollers together at one end to rotate in unison, and adjustable screws N, for preventing the sliding boxes from sliding sufficiently outward to throw the gear-wheels out of mesh, substantially as and for the purposes described.
